The 15-year-old actress shared a video on Instagram of herself on Thursday singing the A Star Is Born tune while swimming in the ocean. Fittingly, she belts out the lyrics, "I'm off the deep end/Watch as I dive in/I'll never meet the ground."
Meanwhile, on Thursday, Mariah Carey revealed that her adorable 8-year-old son, Moroccan, is a huge fan of the British actress. Carey shared a photo of Moroccan doing his best Stranger Things pose while rocking a skeleton costume.
"My son is obsessed with Millie Bobby Brown... can someone please ask her to call him ?☺️," she tweeted.
